Who Must File Louisiana Form IT-540?

Residents, part-year residents, and nonresidents with income from Louisiana sources who are required to file a federal return must also file a Louisiana state income tax return. Even if you did not file a federal return, you may still want to file a Louisiana state income tax return. Individuals who have overpaid their taxes through withholding or estimated payments must file a return to claim a refund. You may also be eligible to claim the Louisiana Earned Income Credit (LA EIC), Refundable Child Care Credit, and other refundable credits.
